Improvement'in Flash-Bbllers, of which the following .V description, in connectionwith the accompanying drawings, is a specification, like letters on the drawings representing like parts.

My invention relates to coil boilers of the flash type or coils thereof.

In the 'drawings illustrating one embodiment of invention, Figure 1 is a vertical' section oi a generator or boiler` illustrating my invention;

view of said boiler; Fig. -3 is a side elevation thereof,

I y the casing'being shown in section.

i In the embodiment of my vigivention selected for illustration herein and shown in the drawings, 4my improved boiler o? generator. comprises a series. of superposcd coils ori grids o, fa, each preferably formed of a single piece of pipe, coiled as many times as desired, the several'coils being suitably connected whereby the incoming water entering preferably at the outermost convolution of `the topmost coil jmay flow downwardly through the several coils and towards the source oi heat,

Obviously,` at some 'point in its travel, .ordinarily about midway the height of the boiler, the water is converted intosteam and i'n thefurther' flow thereof, becomes superheated, issuing in the latter condition froinand at the bottom oi the boiler in the region of greatcstlxeat.

u I v est or lnnemiost convolution, so that the water or steam To prevent gravitation of the water down through th e `several coils, I have formed the latter respectively l, much,like so many truncated cones; in other words, each convolution oi a coil from the outermost convolution inward; is slightly higher than tb c preceding convolution with the highest point preferably at the smallas the'case may be, which in each casein thc boiler shown entersthe outermost .convolution'oi a coil, must travel gradually upward towards and until itreaches the innermost, highest convolution oi the coil before il; may By this construction, each pass to the next coil below. coil becomes, as it were, a trap in itself, to prevent the gravitation of water therethrough; so that even though the connections between succcssive coils be direct and free from any trapping efloct, gravitation of water down through the boiler is'ncvcrthclcss,vprcvcntcd. v

The inncriuost convolution of one coil may beconnectcd with the outcrinost convolution of thc coil bclow, whcrcby water or stcanl may llow from thc loi-incr to thc latter, in any conwnicnt manner, but, l prclcr that such connection iu cach cusc bc byapipo, I), which descends witliin the central (,-yiiudrcul space or cham- Patented Oct. 15, 1907.

ber at the middle of the boiler-and within the circle of the smallest convolution of the several coils, said descending pipe connection being carried outward at the bottom of the boiler, and upward at the outside of the boiler, to the outermostconvolution of the coil to which it is to be connected. By this arrangement, namely,

the carrying oi the several connections' in every instance to the bottom of the boiler, and .upward at the outside thereof, said connections may be made direct,

that is, free from any trapping effect, such as would prevent gravitation of water from one coill to the next below, and also permits-'the several coils to be nested one within and close to the other, thus to provide ina given h' eight a maximum number of coils, which must greatly exceed the number possible in the same height,

- werethe coilsto be separated sufficiently to permit the connection between one coil and the next below to be carried outward between said coils,lrlin'stead of to the bottom of the boiler and then outward.' 1t willbe obs crvcd also that the trapping effect of the several 'Coils is uniform throughout the entire coil; that is, at no point in a coil, does the trapping effect' differ from any other point, excepting insofares may result from the differences in diameter 'of theseveral convolutions of the coil.

My boiler is thus peculiarly adapted for automobile service, where, as will be evident irc-in Fig. 4 of the drawings the boilcr is apt to bc inclined first to one and then lo the opposite side, as upon an uneven roadway or lirst tipped iol-ward and then rearward, as when lesccndng and ascending hills.-

lu Fig. 3, l have shownthc boiler arranged within a suitable inclosing case, C surmonnted by a hood, D, provided with suitable or usual 11p-draft outlet, d, and down draft outlet, d, with the engine exhaust pipe, J2, arranged in thc lutter. This is shown as typical of the arrangement iolmotor vchiclo use; other suitable arrangement may he used in lieu thereof.

My invcnlion obviously is notliinited to the particular cxubodinunit thereof here illustrated, but may be varied within the spirit and scope of the invemion.
